A student wanted to find the volume of dilute hydrochloric acid that would react with 25.0 cm3 of lithium hydroxide solution. They used the equipment in Figure to carry out a rough titration and then a further two accurate titrations. Describe how the rough titration should be carried out once the dilute hydrochloric acid, lithium hydroxide solution and indicator are placed in the apparatus in Figure 7 – 9042

1. First, I read the initial volume on the burette. Then, I opened the tap to let acid flow into the flask containing alkali. While doing this, I swirled the flask to mix the contents. I kept going until the indicator changed colour. Finally, I closed the tap and recorded the final volume on the burette.
